Kayo Thanks for the shout out.
For a really easy to use spoiler, I would agree with going with Reddit's syntax. And, markdown is faster to type than bbcode. But, if anyone likes my accordion bbcode and thinks of a better naming convention / syntax, let me know. I've been thinking about creating shorter versions of all the bbcodes in my extension. So, instead of having to type out [accordion], maybe there could be a short version as well... something like, [ac] or [acrd] ? Same with the tooltip, a version which is simply, "tp" could be added versus typing out "tooltip"... saves a few keystrokes.
Anyway, sorry, I kinda hijacked this thread a bit. Just thinking out loud... Go with Reddit's version for this! 😀
Oh, another related note. My biggest beef with both markdown and bbcode is if you don't know it, especially with custom bbcodes, you have to look up how to do it. The latest editor Flarum uses at least solves this for the basics like bold, italics, link, and so on. But, I wonder if I can figure out how to add a button to the editor (similar to the emoji button) and then a list of bbcode and/or markdown pops up. That'd be sweet.
